A COSMIC CAUSE FOR THE OZONE HOLE?

Wouldn't you know it? Now they are blaming the polar ozone holes on Frank's icy comets -- or something very much like them! M. Dubin and I. Eberstein, two NASA scientists think that small icy comets can account for the seasonal ozone hole and the mysterious polar strato spheric clouds that form during the winter. They propose that ozone molecules bond to tiny ice particles in the winter and, when spring arrives, solar ultra-violet radiation converts water (ice) plus ozone into oxygen and hydroxyl ions.
